Item # KSK000C


Tipping the scales at the 260g mark, Kask's 50 Bike Helmet's not only a feathery option, but incredibly capable in the cooling department, too. This comes in the form of 24 intakes within the in-molded polycarbonate and expanded polystyrene shell.

For fit, the Kask 50 Bike Helmet uses a hinged adjustment system that permits both diameter and up/down adjustment. Together, these modifications cradle the neck and cranium for a bobble-free interface that can be tuned by using either the dial or a finger-push system. A breathable, non-slip gel internal liner sits in between you and the EPS inner to ensure sweat and temperature is kept under control.

Adding to safety, all Kask helmets use a polycarbonate layer that not only covers the shell, but extends to the base ring and on the back, too. The Kask 50 Bike Helmet comes in two sizes, Medium and Large, with multiple color options.

Great helmet!

  • Familiarity: I've used it once or twice and have initial impressions

This is my first road helmet, I have a MTB (specialized) and a bern helmet too, but this one is super light, comfy and looks great!
